Germanan cockroaches Blattela germanica (B. germanica)
is one of the most potential mechanical vectors and
responsible for transmission of many protozoan, bacteria,
viruses and intestinal parasites to humans[1].
German cockroaches can also cause irritation and
allergies in human hosts[2-6]. Based on mentioned above,
control of cockroaches is very important[7,8]. German
cockroaches are becoming resistant to pesticides through
special mechanisms and survive successfully due to quick
adaptation to environment these years[9-16]. The recent
research shows that environmental contamination which is
regarded as a significant contamination does not affect the
cockroaches with pathogenic bacteria[16]. Society urgently
needs to find new materials used as a control tool against
this pest which is pesticide-resistant arsing from high
and irregular use of pesticides in the world. Insulin drugs
are used to the treatment of diabetic patients. This type of
diabetes occurs when the pancreas can not produce enough
insulin to help the body target cells. Paul Langerhans, a
medical student in 1869 during the study in pancreatic
